CFA Equipment Inspection & Maintenance 3 — Questions and Answers
Question 1: A propane-powered forklift has a strong smell of gas near the fuel connection. What should the operator do?
- Continue the inspection while ventilating the area by opening doors
- Shut off the fuel tank valve, move the forklift outside, and notify maintenance (Correct answer)
- Apply water to the connection and check for bubbles to confirm a leak
- Report the smell at the end of the shift in the maintenance log
Correct answer: Shut off the fuel tank valve, move the forklift outside, and notify maintenance
A propane gas smell indicates a potential leak, which is a fire and explosion hazard requiring immediate fuel shutoff, relocation to a safe outdoor area, and maintenance notification.
Question 2: How should a forklift operator check the hydraulic hoses during a pre-shift inspection?
- Remove and reverse the hoses to check for internal blockages
- Visually inspect for cracks, abrasions, bulges, and leaks while avoiding contact with pressurized fluid (Correct answer)
- Pressurize the system to maximum and watch for leaks under stress
- Check hoses only if hydraulic fluid levels are low
Correct answer: Visually inspect for cracks, abrasions, bulges, and leaks while avoiding contact with pressurized fluid
Hoses should be visually inspected for external damage signs; pinhole leaks in pressurized hydraulic hoses can inject fluid under the skin, so hand contact must be avoided.
Question 3: What action should be taken if a crack is discovered in the forklift's overhead guard during inspection?
- Weld it on-site if the crack is small and structural integrity seems intact
- Take the forklift out of service immediately until the guard is repaired by authorized personnel (Correct answer)
- Continue operating with extra caution and report it within 48 hours
- Tape or brace the crack and monitor it for worsening over the next shift
Correct answer: Take the forklift out of service immediately until the guard is repaired by authorized personnel
The overhead guard protects the operator from falling objects, and any crack compromises this protection, requiring immediate removal from service and professional repair.
Question 4: What is the correct procedure when a forklift fails a pre-shift inspection?
- Complete only essential tasks until end of shift, then report defects
- Tag the forklift with a defective tag, lock it out if necessary, and notify the supervisor (Correct answer)
- Assess whether the defect is safety-critical before deciding to report
- Log the defect in the maintenance book and allow the next shift to decide
Correct answer: Tag the forklift with a defective tag, lock it out if necessary, and notify the supervisor
A failed inspection requires the forklift to be tagged out of service, locked out if appropriate, and the supervisor notified — no operation until defects are repaired and the unit is re-inspected.
Question 5: During inspection, the operator finds that one of the mast chains has more slack than the other. This indicates:
- Normal asymmetry due to manufacturing tolerances
- Unequal chain wear or improper adjustment requiring maintenance (Correct answer)
- The chain is over-tensioned and should be loosened
- A minor cosmetic issue that doesn't affect lifting performance
Correct answer: Unequal chain wear or improper adjustment requiring maintenance
Unequal chain slack indicates uneven wear or mispositioning that can cause the forks to tilt unevenly under load, posing a risk of load instability or chain failure.
Question 6: Which of the following is a key indicator that the forklift's brakes need immediate maintenance?
- The forklift takes a slightly longer distance to stop than usual
- Brakes grab immediately with no pedal travel required
- Pedal goes to the floor or the forklift pulls to one side when braking (Correct answer)
- Brakes produce a soft clicking sound during light braking
Correct answer: Pedal goes to the floor or the forklift pulls to one side when braking
A brake pedal that travels to the floor or a forklift that pulls to one side when braking indicates brake system failure, requiring immediate removal from service.
Question 7: When should forklift chains be lubricated?
- Only when rust is visibly present on the chain links
- According to the manufacturer's maintenance schedule or when chains appear dry (Correct answer)
- Exclusively by certified mechanics during annual inspections
- After every load cycle to ensure maximum chain life
Correct answer: According to the manufacturer's maintenance schedule or when chains appear dry
Mast chains should be lubricated per the manufacturer's schedule or when they appear dry to prevent wear, corrosion, and premature failure under load.
